Hello,
The code is still a work-in-progress. The hardware used, the USRP and
DBSRX board, costs as much or slightly more than the RadarBox or
SBS-1. It might be possible to do a simplified hardware board but I
am not a hardware engineer. Mode-S/ADS-B has a 1 Megabit symbol rate
which is way above what a sound card can do.
Nice to hear that it's still in active stage.
Obout the Receiver cost : I understand that, still ...
++ with this we can do some OpenSource and flexible solution
++ Hope ettus will consider to produce 1 port board. I reallize that the
price cut will not that big ... since the core component (i.e : FPGA)
still the same ..... but there is a "cut" anyway :)
About Symbol rate : hmmm what about DVB rx card .... i'm not sure if we
can customize their demodulation to handling mode-s/ads-b ... but they
capable in handling up to 45 megabit/sec symbolrate , and capable of
handling freq around 1 Ghz cmiiw.
Arrrggh ... looks like we need to do firmware work (too many work).
Thanks for your enlightment
